Spatiotemporal distribution of moisture content in sand dunes of the unirrigated forestation along the southern marginal zone of Gurbantunggut Desert
Based on the stationed observation from April to November 2006, the spatiotemporal characteristics of moisture content in sand dunes in the southern marginal zone of the Gurbantunggut Desert were studied. The results indicated that the moisture content in different season was different; the highest was in spring, followed by summer and autumn. Spring was the accumulation period while autumn was moisture shortage period. The moisture content in sand dunes in windward was higher than leeward and showed the same trend as the seasonal change. A dry sand layer 10～20 cm was observed on the surface, the moisture content in different places ranked as dune bottom > top > leeward > windward. The study provided scientific reference to water use and unirrigated forestation in arid area.
